Devices, of whichthe following is a full,

clear, and exact description, reference being had to theaccompanyingdrawings.

This invention relates to wind-shield cleaning devices, the same beingadaptable to analogous uses, such as the cleaning of street carorcarriage Windows or panes of various sorts.

The invention has for its object the attainment of efliciency,simplicity of construction and design, durability, adjustability, andease and convenience of operation, in devices of the aforesaidcharacter.

The embodiment of my invention illustrated in the accompanying drawing'and hereinafter described in detail is primarily intended forincorporation inautomobile wind-shields or the like at thetime of theirmanufacture. Therefore, a further object of the invention is theproduction of a cleaning device throu h which this end may beeconomically an in all respects satisfactorily realized.

In the drawing, Figure 1 is a fragmentary perspective view of awind-shield having the cleaning device of my invention applied thereto;Fig. 2 is a vertical section through the wind-shield and the cleaningdevice, on

the center line of saiddevice; Fig. 3 is a perspective view illustratingthe manner of assembling the device and applying it to the pane of thewind-shield; and Fig. 4: is a sectional detail of the upper end of thedevice and the adjacent portion of the wind-shield, the sameconstituting an enlargement of the upper end of Fig. 2.

Describing the invention by the use of reference characters, 1represents a pane (in the resentinstance, being that of a windshied) and2 a frame or binder therefor. It will be observed that the frame orbinder 2 is, in the present case, tubular, and has its inner edgepressed inward to form a groove for the reception of a channel member 3which, in turn, receives the edge of the pane 1. At a cnnvenien'tlocation along one of its edges, the pane 1 is provided with a notch 4'into which acushion block 5, preferably of rubber, is adapted to fit.Thus block is provided with a notch 6 of inverted key hole shape, andthe sleeve of a bearing member 7 fits sufficiently close within theenlargement of the notch 6 to prevent lateral movement of such member.The bearing member 7 is preferablv formed of a single piece of sheet Ymetaland comprises, besides the aforesaid sleeve, opposed end plates 8which bear upon the opposite sides of the pane. The end plates aresubstantially semi-circular, and their straight sides are engaged bv theinner edges of the channel member 3. This arrangement prevents anyappreciable rocking of the bearing member within the notch 6. It willalso be seen from the construction thus far described, that the bearingmember which constitutes the support of the cleaning device, presentlytobe described, is held in place by the binder 2 (or more accurately,the channel 3 which may be considered a part of the binder) and Withoutthe use of any further means; and that the cushion block 5 is securelyconfined within the notch 4 by the channel 3 and the bearing member 7 Itwill be understood also that the cushion block 5 serves as a shockabsorbing element to relieve-the glass of strains that would otherwisebe imposed upon it by the operation of the cleaner (as willv be betterappreciated further along in this description What I will refer tohereinafter as the frame of the device is designated 10, and the samecomprises a horizontal portion 10", a cleaner carrying branch 16", andan operating branch 10. A stop collar 11 is secured to the horizontalbranch 10*, and the bearing member 7 may be fed up over the operatingbranch 10? and onto the horizontal branch 10, until it engages thestop-collar 11, such manner of assembling being represented by thedottedv line posltions of the bearing member in Fig. 3. It beingpresumed that the cushion block 5 has been applied-to the bearing member7, the assembly may now be applied to the pane by insertingthe cushionblock into the notch 4 with the end plates 8 "occupying positions onopposite sides of the pane, as above explained. The

The cleaner or squeegee is herein shown as comprising a metal binder towhich the numeral 12 is applied. This binder is substantially U-shapedin cross section and between its branches is clamped a strip 13 ofrubber, or similar material, the strip 13 extending some distance-beyondthe open side of the binder 12 and engaging the surface of the pane withenough force to cause it to satisfactorily perform its function ofcleaning the pane when it is moved across the same. The cleaner orsqueegee is attached to the'branch 10 of the frame by a clamp 14, thesame being formed to a metal strap that is bent snugly about the branch10", near its lower end, and is clamped thereto against movement by ascrew .15 which passes freely through one of the branches of the strapand is threaded into the other, suchconstruction being more or lesscommon. Beyond the screw 15, the ends of the strap are separated andshaped to conform to and embrace, rather snugly, the binder 12, thebinder being capable of an adjustment through the clamp when the screwis slightly loosened. A metal loop 17 is attached to the upper end ofthe binder 12 and embraces the branch 10", to hold the cleaner orsqueegee in alinement with the branch, such connection permitting thesqueegee to rock slightly with respect to the branch and thus adjustitselfto differences which may occur in the angular relation between thepane and the branch.

Attention is called to the angular relation of the lower end of theoperating branch 10, to the adjacent surface of the pane 1. A sleeve 20is adapted to be clamped at any position along the aforesaid portion, bya screw 21, which is threaded through the wall of the sleeve and bearsupon the branch. A roller 23, preferably of fiber, is journaled upon thesleeve 20, and bears against and has rolling contact with the innersurface of the pane 1. It will be explained at this time that thehorizontal branch 10 of the frame 10 fits loosely enough within thesleeve of the bearing member 7 to permit it to rock longitudinally ofthe sleeve. With this in mind, 'it will be seen that the pressure withwhich the squeegee bears upon the outer surface of the ane may beregulated by the adjustment 0 the roller 23 along the angular ortion ofthe operating branch 10 of the rame, it being obvious that when theroller occupies an elevated position thereon, that it will force theoperatin branch of the frame farther away from t e pane, consequentlyswinging the branch 10toward the opposite surface thereof; and when theroller occupies a osition nearer the lower end of the operating branch,the other branch is move away from the pane. ThlS adjustment maycompensate forany wear in the cleaner ermitted to strip 13 of thesqueegee, any deformation of the frame 10, or panes of variousthicknesses.

From the foregoing description it will be seen that my inventionprovides a cleaning device that is peculiarly adapted for incorporationin wind-shields at the time of their manufacture; and attention isparticularly called to the fact that, when the device is not in use, itmay occupy a position along and parallel to the frame or binder of thewind-shield, where it is entirely out of the way and presents aneatappearance.

A further decided advantage in my present construction, over formerconstructions which were mounted upon the frame of the wind-shield, 'isthe absence of any protuberance above the frame to interfere with thefit between the upper edge of the wind-shield and the front of thevehicle top.

While I have herein described the present embodiment of my invention indetail, I wish to be understood as not limitin myself to the structuraldetails thereof furt er than is required by the terms of the appendedclaims, and is rendered necessary by the state of the prior art.
